The Comprehensive Antibiotic Resistance Database

A bioinformatic database of resistance genes, their products and associated phenotypes.

3632 Ontology Terms, 2373 Reference Sequences, 898 SNPs, 2213 Publications, 2299 AMR Detection Models


The CARD is a rigorously curated collection of known resistance determinants and associated antibiotics, organized by the Antibiotic Resistance Ontology (ARO) and AMR gene detection models.


The CARD includes tools for analysis of molecular sequences, including BLAST and the Resistance Gene Identifier (RGI) software for prediction of resistome based on homology and SNP models.


CARD data can be downloaded in a number of formats. RGI software is available as a command-line tool. View changes in CARD curation. CARD is updated monthly.
